that i think it would be a great idea. with that we have two other speakers would like to can, ted egan is here from our controller's office to give an economic impact report. >> good morning, supervisors. ted eagan from the controller's office of economic analysis. this morning our office issued an he can economic impact report on this item. you have it in front of you. * i'd like to share some of the highlights with you now. i won't go through again the details of the financing or the construction, but just go straight to how we view this affecting the economy on slide 4. really from a positive side, this will result in construction spending in the near term in san francisco to the tune of about 500 million dollars and in the long run it will make possible for the convention center to accommodate more attendees which will lead to some number of net new visitors in san francisco and increase of visitor spending. to the negative side this has to be paid for and the financing costs both fall in the hotels and on the city which is effectively withdrawing some funds from the local economy.
